Patch

Peanut allergies are one of the most common food allergies, and they can cause deadly reactions. Now, researchers are experimenting with a new peanut protein patch that’s showing some promise. Eight-year-old Joshua Mandelbaum has a very severe peanut allergy, so his mother enrolled him in the study.

Minnesota researchers are trying an experimental way to fix potholes that uses powerful microwaves to heat the patch mix at the very site where the craters develop. As an added dividend, the technology provides a use for taconite waste and recycled asphalt and shingles.
